ANTISKID ATTACHMENT son WHEELS.

Application filedAu gust 2,

T 0 all whom it may concern:

Be it known that 1, John H. HoGsToN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Hinnesota, have invented .a new and useful Antiskid Attachment for Wheels, of which the following is a specification.

This invention relates to antiskid attachments for wheels. 1

The principal object of this invention is to provide an attachment for automobile wheels which will positively prevent skidding. Other objects are to furnish a device which is rugged and durable, and which may be easily attached and detached. A further object is to provide a device which is adaptable to many sizes and types of vehicle wheels.

- A still further object is to provide a tire attachment all of whose parts are connected together so that the attachment is removed and applied as a unit, thereby making it impossible for any of the parts to be either lost or mislaid.

The invention comprises four principal parts, namely, a spoke clamp, a body mem-' ber attached to the spoke clam a chain having one end attached to the body member, and a latch mounted on the body member and engaging the other end of the chain, thereby locking the device in position.

In the accompanying drawing.

.Figure 1 is a sideelevation of a portion of an automobile wheel equipped with my invention; t I

Fig. 2 is a similar elevation looking at the otherside ofthe wheel; I

Fig. 3 is a sectional view on an enlarged scale of the same, the section being taken on the line 33 of Fig. 1;

-Fig. 4 is a sectional view similar to Fig. 3, but taken on the line 4-4 of Fig. 1;

The numeral 10 *in the drawings indicates a spoke of a. wheel, 11 the felly, and 12 the tire. Surrounding the tire ischain 13, which forms part of the antiskid attach-' ment which is my invention. This chain may have any form, but is preferably so made that its links afiord maximum traction with a minimum tendency to cut the I Specification of Letters Patent. Patented J 119 2 2 1920 1918.

tread of the tire. The length of the chain should be sufficient to embrace large as well as small tires. The chain should .fit the tire loosely.

One end 38 of the chain 13 is permanently attached to a felly plate 14, while the other end is free being connected to the felly plate by a latching means which is mounted thereon. The felly plate 14, as its name indicates, is adapted to fit the inner face of the telly 11, and is so shaped that it will not shift its position transversely with respect to the felly.

Permanently secured to the telly plate I is a spoke clamp designated generally by 15. Neither the spoke clamp nor the felly plate is designed to tightly fit its res ective wheelparts, both being provide to hold the chain 13 in position on the tire. It should be here understood that while the drawings show one spoke equipped with the present invention, it is not at all necessary that all the spokes of each wheel be so equipped. Indeed, if every other spoke, or every third spoke has its attachment in place, the wheels will be insured against slipping and will propel the vehicle satisfactorily over icy streets. It should also be understood that while the element 15 is called the spoke clamp, it does not really clamp the spoke but only embraces the same. The function of element 15 is to prevent displacement of chain 13 on the tire.

Spoke clamp 15 consists of sections 16 and 17 which are permanently hinged together. Both sections are alike'in size and form, and have their ends provided with two pairs of eyes 16 and 17 extending half way across their width. These are held in alinement when the clamp embraces the spoke, thus bringing the two sections 16 and 17 together to make up the complete clamp 15.

A pin 29 has one end rigidly secured within one of the eyes 16' of section 16 by a rivet and has its other end 29" enlarged. This pin forms a pintle for the section 17 and at the same time allows the eye 17 0 said section to move or slide longitudinally on it. It will be seen that this construction allows the sections not onl to swing apart or together but also permits the section 17 to be raised with respect to the other or stationary section 16.. It is now clear that eyes 16 and 1? in conjunction with pin 29, form a sliding hinge joint. The construction is very clearly shown in Fig. 6.

The opposite eye 16 also provided with a pin 30, secured by a rivet and extending therefron'n said pin 30 being shorter than pin 29. T he o ji posite eve 17 is ada i teil to lit over the open end of pin 30 when section 17 is slid upon pin 22). The length of pin 29 must be suliiei it to allow for this sliding motion of sect on li'. From what has been said, it is obvious that the elarnp 15 may be detached from spoke ll) by sliding section liup on pins 29 and Sill'until the eye 17' has clearei'l the upper end oi pin Ell) and then swinging it outivardlynpon pin 29 as a pivot. llhe enlarged head 29' prevent-5 the clamp "from coming apart. This form ol spoke-securing nreans has one great advantage: there are no nuts or other parts which can be mislaid or lost, thus renderi 'ig the whole attachment tempm'arily useless. It will be understood that wlien the attachment is in place with the chain connected to the rim plate, the sliding section o the clamp is kept 'lron i moving away 'ill'QIIl the other section by the contact of the sliding section with the riin of the wheel. Ill other words, as long as the chain is connected to the body member and holds the spoke clamp from dro 'iping down on the spoke the sections of said clainp may not heopened.

Each section l6, 17, is faced on its inside with leather strips 18. Instead ol leather. other material, iis r bber, may be used. These strips are secured permanently to their respectlve sections by any suitable ll'lpzlll"flilltfll as rivets lo --and prev nt the attachment from \vei'iring paint oil" the spokes or otherwise disli eruring them. The telly plate ll has a latch plate 2;) secured to it. Preferably the latch p ate 2i) riveted or welded to the inner side of the telly plate and the two ccmstitnte what may be termed as a body member. In order to secure the spoke clamp, the telly plate and the latch plate togcther riyets Zl are run l roi'n the spoke clamp section 16 through the latch phgte 25 A n adapter ll) in the form oii a saddle plate is interposed between the latch face and the spoke'clanip, and is likewise held by rivets 2l. This adapter permits the ronndspoke clamp to be brought close to the latch plate 20 and to be held lirmly thereto. By this construction the spoke clamp, the latch plate andthe 'li'elly plate are com-- bined to :Forni a unitary stri'icture.

The tl elly plate jlalmade from a rectangular piece of ll bent outwardly at two ends to form flan s 25, These flanges allow the telly plate to be seated on and embrace the sides of the tell/ and in to operation with other parts of the device prevent the attaclnnent from shifting transversc'ly with respect to the wheel One side of the folly plate may have a cutaway portion 141-. in which a part of the latch plate .20 may be held so asto strengthen the union between the two parts. The other side ol" the telly plate, the side remote from the spoke clamp, is provided with ears 27, 28, bent inwardly therefrom in a direction opposite to that at which the flanges 253, 26, ex

tend. Each ear has a bore for the reception o'l chain-latching bolts til, 32, described in detail below.

The latch plate 20 re Eerred to above, consists ola double soeketed plate designed to receive, and with the aid o l? bolls 3 l and 32 to hold both ends of chain 13 when the latter surrounds the tire. This double socketed plate is in one piece and is made from a rectangular metal blank having two like rectangular notches or openings 20 cut into the sides thereof at a point about one-third of the way from one e'ndj The short part 22 is bent at right angles to form a leg and the long part 2 is likewise bent. However, part 23 is bent again to form an l -shaped leg whose foot 2% extends entirely across the lielly 'ila te transversely and is riveted, sol dered or welded thereto. The legs 22 and 23 are )erpendicular to the underside of the telly plate. .lieg 22 may simply rest against the telly plate,or may fit into a cutaway portion l i. formed therein.

The foregoing description should not be taken as limiting my invention to the use of a separate telly plate and latch body.

i Tl) admit the ends of locking bolts 31 and 32, h oles are drilled in legs 22 and 23 in line with the bores provided in ears 2?, 28. Bolts 31 and 2-52 are thus slid-able in the re spective ears and the legs. It desirable that only one end of chain 13 he fastened each time the device is attached. Hence, an end link 31) locked in the recess formed between 22 and 23 and bolt 32 is pushed in place. To hold the bolt :1 cotter pin 36 passing through a. hole in the bolt may be provided to bear on the side of ear 28 opposite from that against which the bolt head bears. By such an arrangement, the bolt 32 is held firmly in place, yet can he slid back to disengage the chain end whenever neces sary. Of course, other means than a cotter pin may be used to bring about the same re sult. V i

Bolt Sl is longer than bolt 32 to provide finger room at its outer or head end. A cotterpin-35 or theequivalent, passing through the body the bolt prevents the bolt from being pushed so far in that the fingers cannot grasp it. A coiled spring 33 is mounted on the bolt and bearsat'one'end against ear 2? and at its other end against a Washer 34, or the like, loosely mounted on the bolt. From this description; it is plain that bolt 31 is normally held so as to extend between detachably connected to the spring-actuated.

legs 22 and 23 but may be withdrawn by pulling on its head to admit an end link 38 of the chain.

All that is necessary in attaching the device is to embrace the spoke with the clamp, place the telly plate on the telly, pull the chain around the tire, withdraw the spring bolt and snap the end link in place. In demounting it is only necessary to pull the spring bolt out, when the chain end is released, and then lift up the clamp section as previously described, when the attachment is free of the wheel. There are no nuts, bolts, screws or similar parts which must be removed each time the'device is taken oil.

The attachment is removable as a unit, and
